TLEdata
TLEdata, or two-line element data, is a compact textual format used to convey the orbital parameters of Earth-orbiting satellites. It provides a snapshot of a satellite's orbit at a given epoch and is widely used for rapid propagation of satellite positions using standard orbital models.
A complete TLE entry consists of two lines of ASCII text. Each line begins with a line
The first line contains the satellite catalog number, international designator, epoch time, and terms related to
TLEdata are produced by orbital surveillance networks and distributed by public repositories such as Celestrak and
Limitations include the approximate nature of TLEs and their relatively short predictive horizon. They are most
